To all whom it may concern.'

Be it known that I, ALVARO S. Kno'rz, a citizen of the United States ofAmerica, and resident of Janesville, Rock county, Wisconsin, haveinvented a certain new and useful Improvement in l/Vheeled Implements ofwhich the following is a specification.

My invention relates to wheeled implements in general, but moreparticularly to wheeled plows, and especially those in which the plow issupported by one or more bails, the said bail or bails being in turnmounted on a frame carried by the wheels.

Generally stated, the object of my invention is to provide a novel andeilicient wheeled implement of the foregoing general character.

A special object is to provide a wheeled implement having a depthregulating mechanism whereby no provisions for adjustment of the frontand rear wheels are necessary, the regulation of the depth, as well asthe leveling of the plow, being controlled entirely by a single handlever, and the said lever forming medium of connection between a footlift mechanism and the plow or other working element.

Another object is to provide a novel mechanism for causing the plowv toenter and leave the ground point first, adapted to permit the rear endof the plow to rise and prevent breakage when the plow point strikes anobstruction, and forming a rear connection between the plow beam andframe.

Another object is to provide a stop device for preventing the plow from`iolting up and down when in the ground and under pressure.

A further object is to provide an adjustable connection between thetongue and the front furrow wheel, whereby the position of the tonguerelative to the said wheel can be changed when necessary, or maintainedat the proper angle, as circumstances may require.

To these and other useful ends my invention-consists in mattershereinafter set forth and claimed.

In the accompanying drawings: Figure 1 is a plan of a wheeled plowembodying the principles of my invention. Fig. 2 is an enlarged detailsection on line 2-2 in Fig. 1. Fig. 3 is an enlarged perspective of theadjustable tongue connection which forms one feature of my invention.Fig. 4 is a landside elevation of the said plow, showing the land-sidewheel removed for convenience of illustration, but dotted in to show theposition thereof during operation of said plow. Fig. 5 is a longitudinalsection on line 55 in Fig. l, showing the plow leaving the ground, (infull lines) and indicating in dotted lines the position of the plow whenit strikes an obstruction, or when it enters the ground. Fig. 6 is adetail section on line 6-6 in Fig. 8. Fig. 7 is a similar section online 7 7 in Fig. 8. Fig. 8 is an enlarged rear elevation'of the raisingand lowering means, and also the depth regulating mechanism shown inFig. 1, showing a portion of the land-side wheel. Fig. 9 is a detailsection on line 9-9 in Fig. 8*. Fig. 10 isa detail section on line 10-10in Fig. 7 Fig. 11 is a detail section on line 11-11 in Fig. 6. Fig. 12is a view similar to Fig. 5, but showing the plo-w raised out of theground. Fig. 13 is a view similar to Fig. 8, but showing another form ofmy invention. Fig. 14 is a section on line 14?-14 in Fig. 13. Fig. 15 isa section on line 15-15 in Fig. 14.

As thus illustrated, my invention comprises a body frame r1 supportedhorizontally by the front and rear furrow wheels B and C, ,and by theland-side wheel D. The plow E has a beam c carried on the bail F whichis mounted to turn in bearings 7 and f1 on the frame.

The foot lift mechanism comprises a lifting lever G and a depressinglever g rigidly connected together in the manner shown in Fig. 7, andheld thus by a bolt g1 extending from one to the other through thesleeve g2 that turns in the top of the bearing bracket f1 on the frame.The said bracket is formed with a shoulder Q3 and a notch g4, adapted tobe engaged by a spring catch g5 on the lever g, whereby the plow islocked down when the lever is as shown in Fig. 7, or up when the leversswing back and the catch engages the notch g4. The arm g" is rigid withthe lever g, and is connected by a link g7 with the arm g8, which latteris rigid with a sleeve gf) on the straight outer portion f2 of the bail.

One feature of my invention comprises the arm g1 which is rigid with thesleeve 99 and which is provided with a set screw g for engaging the stop912 of the bearing bracket f1 on the frame. By this construc tion thedownward movement of the arm gs is limited, and the weight of theplow,when down, is not on the link 97, but on the frame. In this way thefoot lift mechanism is relieved of the strain. In other words, the

plow is held at a iXed depth, and does not ride out in hard spots, eventhough the connections involving the link g7 are more or less loose. Theset screw f/u takes up the or looseness, so to speak, and prevents theplow from jumping up and down. lhen the plow' is down as shown in Fig.7, the pivotal joints 913, Q14 and g15 are in line, and with the joint014 thus on center, the plow is held down, and the weight of the plow ison the set screw g, instead of on the link Q7, when the said screw isproperly adjusted.. Thus the pressure against the stop g1g relieves thestrain on the foot lift mechanism, when the plow is' in the ground. Thescrew g1 on the link (/7 engages a stop ,(/17 on the'arm gs, to limitthe movement of the joint g1* toward the rear of the plow.

Another feature of my invention cour prises the hand lever H which 'isrigidly keyed to the bail portion f2 (see Figs. S and 9) and which isprovided with a short ai'm it having three bolt holes 71.1. The arm h2is loose on the portion f2, but is connected rigidly with the arm L by abolt 7b3 inserted through the middle one of said holes h1. The offsetaXle (l is rigid with said arm h2, and supports the land-side wheel D.For ordinary purposes this adjustment of the joints is employed; butextreme positions of the plow up and down may be obtained by shiftingthe bolt h3 to one of the other holes, and for unusually deep plowingthe bolt will be set in theuppermost hole k1 and for unusually shallowplowing, in the lowermost hole. yThus the hand lever H is available forassisting the lever G in raising the plow out of the ground, and theadjustable ccnnection between this lever and the offset axle of theland-side wheel permits the plow to operate at different depths. But ineach case the lever G has the same throw or range of movement.

A further feature of my invention comprises the curved rack arrangementI which is rigid with the sleeve gg, which latter is loose on the bailportion f2, and a spring catch 1I on the lever H, said catch beingcontrolled by the usual means on the upper end of said lever. Thus thelever H can be set in different positions relative to the rack I, andthis changes the angle of the bail F relative to the arm g8, permittingthe plow to assume a higher or lower working position. In this way thedepth of the furrow is regulated, and asl the operation of said lever yHserves also to vary the angle of the aXle arm h2, an arrangement of thischaractei' serves also for leveling the plow. If the depth is not right,when lever H reaches the l limit of the rack in either direction, then afurther adjustment for this purpose is obtained by the holes tl .andbolt ha, in the manner previously explained.

The means for supporting the rear end of the plow, and for causing theplow to enter and leave the ground point first, constitutes anadditional feature of my invention. This comprises the member orsocalled bail J pivoted tov the lower ends of the brackets j, Vto swingup and down at its upper end. The bracket jl on the plow beam isconnected by the link y'2 with the upper end of said member J, in themanner shown. Preferably the relative arrangement and proportions aresuch that the member J never reaches a horizontal position, but alwaysstands at an angle. This is further insured by the stop l7'3 on theframe, upon which stop the member J rests when down, being provided witha lateral projection J1 for engaging said stop. By this provision thedownward motion of the member J is caused to cease a little before thebail F reaches its lower position for normal depth. lf the plow is thenlowered to a' greater depth, it will be tilted forward with its pointdownward. When the plow starts to rise, the link jg swings backward adistance before reaching a 'position which causes the member J torise,the two elements being relatively formed for this purpose. This enablesthe plow point to tilt upward, so that the plow comes out of the groundpoint first, as shown in Fig. 5. As the lifting movement of the plowcontinues, by downward movement of the lever G, the member J is forcedupward and' into the position shown in Fig. 12. Preferably, the link,7'2 has a projection l7'4 at its upper end, which at times will engagethe stop j on the member J, as shown'in dotted linesv in Fig. 5, tolimit the upward movement of the rear end of the plow, when it tilts inthis direction, as in entering hard ground.

The front and rear wheels B and C have their stems or standardsconnected by a rod K, in the usual way, whereby the tongue L controlsthe rear caster wheel C as well as the said front wheel. rFor thispurpose the said rod is secured to a crank arm c on the upper end of thestem or standard o1 of the rear wheel, and the front end of said rod isarranged to slide in the slot in the arm cl fixed on the upper end ofthe stem b of the front wheel. This sliding movement of the end of therod in the slot 7o is in opposition to the spring 7a2, in the usualmanner, and o ndly occurs when the tongue swings to one s1 e.V

Another feature of my invention comprises1 the curved rack 7c3, adaptedto be engaged at different points bythe spring catch 704, and rigid withthe sleeve 765 on the stem 72 of the front wheel. Said sleeve 7:5 is notfastened to the stem o, but is free to turn thereon. The tongue L isconnected by a horizontal bolt 7c with the arm 7c which rigidly connectsor unites the rack 7c3 with the sleeve 705, whereby the latter must turnwhen the tongue swings sidewise, although the tongue can swing up anddown. The arm 701, being locked to the rack 7c3 bythe catch 714, mustalso turn when the tongue swings sidewise, and hence the front wheelturns to right and left with the tongue. The angle of the tongue,relative to the wheel B, can be changed at will, by releasing the catch716%, and in this way the front wheel can be positioned to suit therequirements. The rear wheel is held against movement to right or leftwhile the plow is traveling straight ahead, but the side swing of thetongue releases the rear wheel, to a certain extent, because of theangular position of the slot 7c when the tongue is swung to one side.Thus the wheels B and C can, have the same or different angles, and thefront wheel can be turned to either side, while the tongue remainsstraight; or, if necessary, the tongue can be swung to one side withoutdisturbing the position of the wheels. The said tongue, however, isfixed to the member 748, which latter engages the bolt 706, and theadjustment is obtained without disturbing the connection between thesaid member 768 and the tongue. Thus the draft pin or bolt 7c is alwaysat right angles to the tongue, or at some fixed angle thereto.

Suitable provisions e1 are made at the end of the beam e for the draft,the plow being what is ordinarily known as a single bail plow, therebeing no bail for the front end of the beam. Also, and in the usualmanner, a spring N connects the frame with the bail E, thereby assistingin lifting the plow, and the drivers seat O is in the usual position. Asshown in Figs. 13, l-t and 15, the construction is substantially thesame as that previously described. In this case, however, the arm 7L2 isprovided with a hand lever M, and the lever H (previously described) isprovided with a rack my, said lever M having a catch m1 for engagingsaid rack. This takes the place of the arm 7L, holes 701 and bolt 71,3(previously described),

and in addition enables the operator to change the angle of the arm 71,2while the plow is in operation. The said rack has three notches m2 whichcorrespond to the said three holes h1, and which afford intermediate andextreme up and down positions for the bail portion f1, relative to thelandside wheel. In other words, the hand lever M can be employed forcontrolling the landside wheel independently of the bail and plow,whenever this is found necessary or desirable. Ordinarily, however, thelever H is suiiicient for all purposes and the lever M is providedmerely to satisfy the requirements in exceptional cases.

The hand lever H is not only a depth regulating lever, of course, but isalso a leveling device as well, inasmuch as the body frame is supportedat a fixed height on the front and rear furrow wheels, and whateverleveling action takes place is accomplished bythe control exercised bysaid hand lever over the land-side wheel. When the plow is set at alower depth the land-side wheel rises relative to the frame, and whenthe plow is set for a shallow furrow the said wheel takes a positionlower down relative to said frame. This, of course, tends to keep theframe level, and to that extent the wheeled plow is in one senseself-leveling, inasmuch as the leveling action is not dependent upon aseparate operation, but to the contrary is included in the raising andlowering of the plow by the rocking of the front bail thereof.

With further respect to the arrangement whereby the bottom of the furrowis kept level, it will be understood, of course, that merely keeping theframe level does not, in a wheeled implement of this character,necessarily mean that the bottom of the furrow will be level. Whetherthe bottom ofthe furrow is level, depends, of course, upon whether thecutting edge of the plowshare is maintained in a horizontal plane.Referring to Fig. l, and as is well known, this cutting edge extendsobliquely to the line of travel, when the plow is viewed from above, andit follows that a tilting of the plow beam onV the bail will so changethe position of this cutting edge that the furrow is no longer level. Asstated, therefore, the level condition of the bottom of the furrow doesnot necessarily result from merely keeping the wheeled frame level, andis dependent upon a coperation of the bail and the offset axle, as wellas the action of the rear supporting mechanism for the plow-beam. lliththe herein shown and described construction, and as previously stated,the hand lever H is something more than a depth regulating' lever.inasmuch as the frame A is supported at a fixed height on the wheels Band C, whereby the said hand lever must also control the bail and offsetaxle in a manner to insure a level furrow bottom for all depthadjustments of the plow. It is also true, for the reasons previouslygiven, that the rear support .l and its link jg contribute to theleveling of the plow to insure a level bottom for the furrow, inasmuchas this is something that is dependent to some extent upon the positionof the plow-beam on the bail F; for while the offset axle might keep theframe level during up and down adjustment of the plow to vary the Vsatom of the furrow was not level because ofy the tilted position of theplow-beam on the bail-that is to say, because of therfact that thecutting edge of the plowshare was not traveling in a horizontal plane.As stated, therefore, the keeping of the bottom of the furrow level issomething that depends upon the proper coperation of the bail and offsetaxle and rear swinging support for the plowbeam; for, in order to keepthe cutting edge of the plow in a horizontal plane, at any desireddepth, and with diderent degrees of suck for the plow, it is necessarythat the tilting of the frame about a longitudinal axis be controlled inthe right manner, andy that the tilting of the plow about a transverseaxis be also controlled for the purpose of keeping the cutting edge ofthe plowshare in a horizontal plane. l.Vith the construction shown anddescribed, these elements are desirably so arranged lthat they coperateto keep the plow level, thereby insuring a level bottom for the furrowregardless of the depth thereof, and thus the hand lever H is employedfor rocking the bail and axle to vary the depth in a wheeled plow which,because it has no special or separate hand lever or other device forleveling purposes, is practically self leveling in character; for, withthe construction shown and described, there is no adjustment of theplow, other than the rocking of the front bail to vary the depth, whichmight tend to disturb the level condition of the plow-bottom, and itfollows that whatever leveling is done must be accomplished by the saidhand lever H as something incidental to its primary function ofregulating the depth.

In order to plow deeper, the wheel D must move upward relative to thefurrow, and to plow a more shallow furrow the said wheel must movedownward relative to said frame, which is necessary in addition to theup and down adjustment of the beam in the frame, as the plow bottom mustalways be level with the bottom of the front and rear furrow wheels, andthe land wheel must always travel on the high or unplowed ground.

The element F is commonly termed a bail,4

but in effect it is a rock shaftor crank shaft, and hence a crank shaftof any suitable character can be employed for this purpose.

F or the broader purpose of my invention, I do not limit myself to anyparticular form of plow, nor to any particular number of bails for theplow beam. These are things that can be changed or modified withoutdeparting from the spirit of my invention, Also, l do not limit myselfto the exact construction shown and described.
